[RPI4] HDR video on SDR TV

Help and Support Raspberry Pi
1

Hello,

I have OSMC installed on a Raspberry Pi 4 which is plugged into a 2014 Samsung TV. I have a problem, the colors of HDR videos are dull on my TV. With VLC on my laptop, without an HDR screen, the video colors are fine. Is there an option in the settings for better color conversion? Or is it that RPI4 doesn’t support this conversion?

  • Video format: hevc (Main 10), yuv420p10le(tv, bt2020nc/bt2020/smpte2084), 1920x800 [SAR 1:1 DAR 12:5], 23.98 fps, 23.98 tbr, 1k tbn (default)
  • Line in Logs: ffmpeg[0xdb428550]: [swscaler] No accelerated colorspace conversion found from yuv420p to bgra.
  • Version: OSMC 2024.08-1 (I had the same problem with Kodi 20)

Pi doesn’t have any tonemapping hardware, so this is expected.

Just a suggestion…
If you are using a Pi 4 make sure that you are using the HDMI output closest to the power plug. I and others have seen washed-out colours from the other output.

Indeed, but if the TV does not support HDR and the content is in HDR, there is not much that can be done.
